spring - jms 连接工厂 javax.naming.NamingException : Could not create resource factory instance

Question

您好，我正在尝试从 Tomcat 8 连接 WebSphere IBM MQ 7.5.0.7 连接工厂。启动 tomcat 服务器时，我们加载 spring XML，从中我们连接到 IBM MQ 连接工厂。

下面是spring xml中的代码。

<bean name="jmsConnectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
            <property name="jndiName" value="java:comp/env/JMS/QFX_PF1UATMQCF" />
        </bean>

Tomcat 中 Context.xml 中的代码。

<Resource name="JMS/QFX_PF1UATMQCF"
        auth="Container"
        type="com.ibm.mq.jms.MQQueueConnectionFactory"
        factory="com.ibm.mq.jms.MQQueueConnectionFactoryFactory"
        description="JMS Queue Connection Factory for sending messages"
        HOST="some hostname"
        PORT="1425"
        CHAN="SYSTEM.DEF.SVRCONN"
        TRAN="1"
        QMGR="EUQFXP7A"/>   

下面是我在启动 tomcat 时遇到的异常。

 Cannot resolve reference to bean 'jmsConnectionFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jmsConnectionFactory' defined in class path resource : Invocation of init method failed; nested exception is javax.naming.NamingException: Could not create resource factory instance [Root exception is java.lang.NoClassDefFoundError: javax/jms/JMSException]

Answer 1

您至少需要将以下 JAR 文件复制到 Tomcat(例如 $CATALINA_BASE/lib):

• > jms.jar
• > com.ibm.mq.allclient.jar

正如@JoshMc 提到的，您不应该再使用 MQ 7.5。

启动 Tomcat 时，您可能会在 catalina.log 中看到 WARNING 消息，如下所示:

24-Feb-2018 22:06:40.473 WARNING [localhost-startStop-1] org.apache.tomcat.util.scan.StandardJarScanner.processURLs Failed to scan [file:.../lib/jms.jar] from classloader hierarchy
 java.io.FileNotFoundException: .../lib/jms.jar (The system cannot find the file specified)
        at java.util.zip.ZipFile.open(Native Method)
        at java.util.zip.ZipFile.<init>(ZipFile.java:219)

您可以通过将 MQ jar 添加到 catalina.properties 中的 tomcat.util.scan.StandardJarScanFilter.jarsToSkip 属性来消除这些警告。
